• A. Ulsoor lake, Karnataka
• B. Lonar lake, Maharashtra
• C. Vembanad lake, Kerala
• D. Sagar lake, Madhya Pradesh

Answer 1

The Correct Option is C

Concept: This question tests geographical facts regarding India's major water bodies and hydrological landmarks. Let us evaluate the unique geographical profile of each lake listed in the options:
• Option (A) Ulsoor lake, Karnataka: A relatively small, artificial lake located in the heart of Bengaluru city, used primarily for recreation.
• Option (B) Lonar lake, Maharashtra: A notable crater lake created by a meteor impact in basaltic rock. It is famous for its unique alkaline chemistry, but it is circular and relatively small.
• Option (C) Vembanad lake, Kerala: Spanning across several districts in Kerala (including Alappuzha, Kottayam, and Ernakulam), it stretches over an exceptional length of approximately 96.5 kilometers. This makes it undeniably the longest lake in India and the largest lake in the state of Kerala. It is also the venue for the famous Nehru Trophy Boat Race.
• Option (D) Sagar lake, Madhya Pradesh: Also known as Lakha Banjara Lake, it is located in Sagar district and is not among the largest or longest lakes in the country. Thus, Vembanad Lake matches the criteria perfectly, making Option (C) the correct choice.
